Maryland Tax Refund

Option 1: If you don't owe MD taxes or expect a tax refund and don't file by the April deadline, you would not face a late filing penalty. However, your refund might expire if you do not file a tax return within a certain time period. Thus, eFile your tax return by the April or the October deadline and claim your MD tax refund.

Option 2: If you have e-filed a federal tax extension and do not anticipate owing Maryland income tax or receiving a refund by the state tax deadline, your federal extension will be automatically accepted as a state extension. There is no need to submit Form PV.

Owe Maryland Taxes

Option 1:Pay your Maryland income taxes online at Maryland taxes.

Option 2: If you owe MD Taxes, file either your Maryland tax return or MD tax extension - even if you can't afford to pay all or some of your MD taxes due. Alternatively, you can pay your MD taxes due online by the April deadline. In that case, you don't have to file an extension by the April deadline since your taxes are paid in full. In case you filed an extension by April, eFile your MD return by the October e-file deadline as you can no longer e-file your returns and would have to submit a paper return past this date.

Note: Failure to pay taxes due or electronically file a tax return by the October deadline will result in late filing penalties.

Option 3: Complete Form PV, include a check or money order, and mail both to the address provided on Form PV.

Important: Even with an extension, you must e-file or mail your MD tax return by the October deadline.

Tax Penalties
Important: If you owe Maryland and/or IRS income taxes and do not file an IRS and Maryland tax return or extension by the Tax Due Date, you will be subject to IRS and MD late filing penalties. Estimate IRS late filing, payment penalties. In addition, if you do not pay your taxes by the Tax deadline, you will be subject to late tax payment penalties. Filing an extension on time will ONLY eliminate the late filing penalties but not the late tax payment penalties. Late filing penalties are generally higher than late payment penalties, thus file something on time even if you can't pay anything on time!
